What social skills are important to militia captains? The ones I think might be, but have no way of confirming are:
- Leadership
- Organization
- Teacher
Are these used by militia captains? If not, are any social skills at all?
Those aren't social skills, they're used in military training, or (in the case of organization) used by an appointed manager.
None of the social skills (such as comedian, liar, flatterer, etc.) have any bearing on military ability, except in cases where an increase in those social skills result in a physical attribute increase.
So what do Teacher and Student do? Teacher's lead better demonstrations (so more skill ups, faster) and Student's learn better from demonstrations (again, more skill ups, faster).
